Repeated constant work-rate (CWR) tests to capture intra-individual variability (IIV) associated with critical power (CP) and curvature constant (W′) estimates. The dotted, dashed, and dot-dashed lines show the fits to the different sets of data and their respective asymptotes. The grand means for CP and W′ are obtained by averaging the respective parameters estimates from each curve fitting
